Service Positioning
We provide Chinese manufacturers building factories in Thailand with an integrated China–Thailand service covering everything from company incorporation to pre-production approvals. Registration is not treated as just a business licence: we work backwards from your target start-of-production date and put company incorporation, BOI, the factory licence, equipment import and staff visas on a single schedule, with one team carrying it through to the end. After production starts, bookkeeping and tax filing, BOI compliance and audit follow on without a hand-over gap.
Scope of Services: What Is and Is Not Included
| Handled by Z&X | Not included in this service |
|---|---|
| Company incorporation: name reservation, articles of association, shareholder registration, certificate of incorporation, company seal | Outbound investment filing and foreign-exchange registration in China |
| Registrations: VAT (PP.20), social security, customs import/export registration, accompanied bank account opening | Factory site selection, construction and environmental impact assessment |
| BOI investment promotion application: eligibility and category assessment, application documents, interview preparation | Customs clearance (handled by the customs broker you appoint; Z&X handles import release filings in the BOI system and supports clearance) |
| Post-approval BOI filings: machinery master list, maximum raw material stock and production formulas, import release filings | Government fees, translation, certification and other third-party costs (borne by the company at actual cost) |
| Factory licence: determining the factory category, preparing the application, accompanying the factory inspection | Work visas and work permits for non-BOI companies |
| Foreign staff: visas and work permits for management and technical staff of BOI companies | Any guarantee of BOI approval or bank account approval (subject to review by the authorities and the bank) |
| Overall coordination: a schedule worked back from the production date, weekly progress reports, item-by-item sign-off on a delivery checklist | |
| After production starts: bookkeeping and tax filing, BOI write-off and reporting, annual audit (engaged separately) |
How Z&X Differs from a Standard Registration Service
| Point of comparison | Standard registration service | Z&X |
|---|---|---|
| Where the service ends | Ends once the business licence is issued | Ends when you are able to produce: the factory licence, duty-free machinery import and the arrival of foreign staff are all on the schedule |
| Team background | Mainly company secretarial and agency work | Led by advisers with manufacturing finance backgrounds: Biaoshun Jia, General Manager of the EEC Branch, has 12 years of finance and tax experience, more than ten of them at large manufacturers in Thailand and as CFO of a Chinese listed company; his EEC team has served more than 50 large manufacturers |
| Location | Mostly in Bangkok, far from the factory | EEC Branch opened in Chonburi in 2025, close to the eastern industrial estates |
| Link to BOI | Registration and BOI are handled by different firms, so things fall through the cracks at hand-over | Incorporation, the BOI application, machinery lists, write-off and reporting are handled by the same team; Z&X has completed 100+ BOI projects |
| Link to head office in China | Works only on the Thai side | “Two countries, three firms”: Zhongxin (China) Tax Agents, Zhongxin (Thailand) Accounting and Zhongxin (Thailand) Audit can align with your head office's finance and tax requirements at the same time |
| How progress is delivered | Verbal updates | Parallel schedule plus item-by-item sign-off on a delivery checklist, so every step can be verified (Z&X CODE compliance-growth model) |
Common Concerns of Chinese Manufacturers and How Z&X Addresses Them
| Common concern | How Z&X handles it |
|---|---|
| Will our registration documents (shareholder identities, source of funds, technical and process information) leak? | Four confidentiality measures: ① a non-disclosure agreement is signed together with the engagement; ② each project has a dedicated file, accessible only to project team members; ③ documents are used only for this project's government filings; ④ at the end of the project originals are returned against a checklist, and electronic copies are kept or deleted as agreed |
| We cannot see progress or where things are stuck | A schedule is issued on signing, with the responsible party and deadline for each item; progress is reported weekly, and any delay is explained the same day with a recovery plan |
| Costs exceed the budget | The quotation lists service fees separately from government fees, translation, certification and other third-party costs; third-party costs are settled at actual cost against receipts |
| What if an approval is not granted? | We explain in advance which outcomes depend on review by the authorities; if documents are returned, we promptly explain why and give a correction plan and timeline |
| No one follows up after registration, so compliance breaks down | The same team continues with BOI compliance, bookkeeping, tax filing and audit, with a written hand-over checklist |
| Language barriers with Thai authorities | Chinese-speaking advisers work with you throughout, Thai specialists deal with government agencies, and key documents come with a Chinese explanation |
Which Chinese Manufacturers This Service Fits
| Your situation | What Z&X focuses on |
|---|---|
| Building a factory in Thailand for the first time, with a head office unfamiliar with Thai approvals | Explaining every step in Chinese and providing an overall schedule worked back from the production date |
| Production projects planning to apply for BOI | One team linking incorporation, the BOI application, machinery lists and post-approval compliance |
| Projects located in the Eastern Economic Corridor (Chonburi, Rayong, Chachoengsao) | Close follow-up by the Chonburi EEC Branch |
| Production projects that need to enter local supply chains and pass customer factory audits | Designing the entity, shareholding and finance system from the start to meet customer audit requirements and the standards of a listed company's subsidiary |
Service Process: From Assessment to Start of Production
Assessment → Backward schedule → Incorporation ‖ BOI application → Factory and factory licence → Machinery list filing and import → Staff visas → Production → Tax and BOI compliance
| Step | What Z&X does | What the company provides | Output of this step |
|---|---|---|---|
| 1. Needs assessment | Understand products and processes, investment size, target production date and preferred location; assess BOI eligibility and category, foreign shareholding and registered capital | Project overview, shareholder background, equipment and staffing plans | Assessment: recommended route, decisions to make first, approximate timeline |
| 2. Plan and backward schedule | Work back from the production date across incorporation, BOI, factory, factory licence, equipment import and staff visas | Confirm entity, shareholding and scope of service | Written plan, overall schedule, quotation |
| 3. Incorporation and registrations | Name reservation, registration, accompanied bank account opening, VAT and social security registration, customs registration | Shareholder and director documents, paid-up capital, director present to open the bank account | Business licence and registrations (company registration about 2 weeks) |
| 4. BOI application | Application documents, business plan and financial projections, interview preparation, follow-up on approval | Product and process description, equipment list, staffing plan; responsible person attends the interview | BOI approval and promotion certificate |
| 5. Post-approval filings | Machinery master list (review of a new list can take up to about 60 working days, so it should be filed before the first equipment arrives), raw material and production formula filings | Equipment specifications, arrival plan, raw material usage data | Approved filings, allowing duty-free import shipment by shipment |
| 6. Factory licence | Determine the factory category, prepare documents, accompany the inspection | Factory and equipment ready for inspection | Factory licence (where required, formal production cannot start before it is issued) |
| 7. Staff visas | Position approval, visas and work permits for foreign management and technical staff of BOI companies | Staff documents, arrival dates | Foreign staff working legally |
| 8. Pre-production check and hand-over | Check that all registrations, licences and filings are complete, and hand over documents against the checklist | Sign off the delivery checklist | Complete documents and government receipts |
| 9. After production starts (engaged separately) | Bookkeeping and tax filing, BOI write-off and reporting, annual audit | — | Ongoing compliance |
The above describes typical cases; actual timing follows the project schedule and depends on the authorities' review speed, completeness of documents and project complexity.
